Few members of the Star Wars family are as active on social media as Mark Hamill, who constantly interacts with fans and pokes fun at topics other Twitter users are engaged with. When a Twitter user asked Hamill about the story behind an interesting behind-the-scenes photo while also teasing the actor, Hamill shed light on what the reality was behind the photo.

Did you feel safe with all those mattresses under you? @HamillHimself #healthandsafety pic.twitter.com/wzMnx1W7q0

The photo shows the iconic conflict between Darth Vader and Luke Skywalker that takes place at the end of The Empire Strikes Back, with Vader revealing Skywalker’s true lineage. In the finished film, the conflict appeared to take place above a huge mechanical chasm in Cloud City, which left Luke with no place to go once he was cornered.

The behind-the-scenes photo reveals that, instead of filming the sequence thousands of feet in the air, it took place over a massive pile of mattresses as a precaution in case Hamill or Darth Vader actor David Prowse might have slipped.

At first glance, it appears as though the mattresses were stacked merely a few feet below the actors, giving the impression that the actors might have been overly precautious. That’s where Hamill stepped in to shed insight into the picture.

Always felt safe. But check-out stuntman spotting me in background for perspective. Mattresses much further down than they appear! #ESSplathttps://t.co/SCXiijWe9U

In the original trilogy, Hamill was required to perform a variety of incredibly athletic stunts, ranging from intense training sequences on Dagobah with Yoda to elaborate lightsaber choreography in battles with Darth Vader in Return of the Jedi.
